DIRECTIONS: The followingitems consist of two statements, Statement I ...
Explanation:
Statement I: Colour of nitrogen dioxide changes to colourless at low temperature.
This statement is true. Nitrogen dioxide (NO2) is a reddish-brown gas at room temperature and it is a strong oxidizing agent. However, at low temperatures, below -11.2°C, nitrogen dioxide undergoes dimerization to form dinitrogen tetroxide (N2O4), which is a colorless gas. The reaction can be represented as follows:
2NO2 ⇌ N2O4
Therefore, the color of nitrogen dioxide changes to colorless at low temperature.
Statement II: At low temperature Nitrogen tetroxide (N2O4) is formed which is colourless.
This statement is also true. As mentioned earlier, nitrogen dioxide (NO2) dimerizes at low temperatures to form dinitrogen tetroxide (N2O4), which is a colorless gas. This process is reversible and the reaction can be represented as follows:
2NO2 ⇌ N2O4
Therefore, at low temperatures, nitrogen tetroxide (N2O4) is formed, and it is indeed colorless.
Explanation of the Relationship:
Both statements I and II are individually true and statement II is the correct explanation of statement I. The color change from reddish-brown to colorless in nitrogen dioxide is due to the formation of dinitrogen tetroxide at low temperatures. The dimerization reaction between two molecules of nitrogen dioxide leads to the formation of dinitrogen tetroxide, which is a colorless gas. Therefore, the color change is a result of the formation of a different compound with different physical properties.
Conclusion:
Based on the above analysis, option 'A' is the correct answer. Both statements I and II are individually true, and statement II is the correct explanation of statement I.
